Use JQ to get a csv list of assets in aws with security groups, names, and ENI ID for tracking VPC Flows from JSON

cat aws.json | jq -r '.Reservations[].Instances[] | [.PrivateIpAddress, .SecurityGroups[].GroupId,.SecurityGroups[].GroupName,.NetworkInterfaces[].NetworkInterfaceId,(.Tags[] | select(.Key =="Name") | .Value),([.InstanceId| tostring] | join(";"))]|@csv'
You need to use the aws ec2 describe instances to get the JSON file.

What Others Think
